| Abstract: | The effect of nature of inoculum on disease induced by Fusarium oxysporum f.sp. lycopersici on tomato was tested. Chlamydospores produced in soil 30 days after inoculation induced a more severe disease than microconidia indicating a higher inoculum potential of chlamydospores.
The method proposed produces easily an inoculum of F. oxysporum f.sp. lycopersici which infects the plants consistently and induces a relatively high disease severity. |
